The Gothic Roupov castle was founded in the 13th century, and after a Renaissance modernization was one of the most beautiful Czech castles. The now completely standing part was built later and is being used by the current owners, the old ruined part hides many original architectural pieces, and is freely accesible. The original black kitchen with a medieval chimney is still present, and a gothique well. The castle was in usable state in the late 18th century, but slowly deteriorated, and the old part was disassembled for stone when a nearby village burned down and building material was needed. Some walls collapsed in 1817 and the castle became a ruin. Today the old part is conserved.References:
The Basilica of Santa Maria in Trastevere is one of the oldest churches of Rome. The basic floor plan and wall structure of the church date back to the 340s, and much of the structure to 1140-43. The first sanctuary was built in 221 and 227 by Pope Callixtus I and later completed by Pope Julius I.
The inscription on the episcopal throne states that this is the first church in Rome dedicated to Mary, mother of Jesus, although some claim that privilege belongs to the Basilica di Santa Maria Maggiore. A Christian house-church was founded here about 220 by Pope Saint Callixtus I (217-222) on the site of the Taberna meritoria, a refuge for retired soldiers. The area was made available for Christian use by Emperor Alexander Severus when he settled a dispute between the Christians and tavern-keepers.
The church underwent two restorations in the fifth and eighth centuries and in 1140-43 it was re-erected on its old foundations under Pope Innocent II.
